摘要： The invention concerns an implantable heart monitoring device (10) comprising, inter alia, a control circuit (14) configured to be able to measure an impedance across at least part of an atrium, such that the variation of the impedance is related to the volume change of the atrium. The control circuit (14) is configured to carry out certain steps, and to store values at different occasions that indicate the rate of change of the meas¬ ured impedance. The stored values have been determined such that, when the device (10) is used in a living being, the variation of the stored values will be related to the variation of the speed with which the atrium is filled with blood during the atrial dias¬ tole. The invention also concerns a corresponding system and method.

摘要： A device and method of a medical implant for monitoring progression of heart failure in a human heart. An activity sensor provides information related to the activity level of a patient and an oxygen sensor provides information related to the level of oxygen content in venous blood. A determined level of venous oxygen content at a determined activity level is obtained, and that level of venous oxygen content is compared to stored values at a corresponding activity level. The result of the comparison is used as a basis for determining a degree of heart failure.

摘要： The invention relates to ventricular tachyarrhythmia detection and classification. Upon detection of a ventricular tachyarrhythmia based on an electrocardiogram signal, cardiogenic impedance data representative of ventricular volume dynamics are collected and used for classifying the detected tachyarrhythmia as stable or unstable. In the latter case but typically not in the former case, defibrillation shocks or other forms of therapy are applied to combat the unstable ventricular tachyarrhythmia.
